What you see in the gallery above are 32 allegedly leaked pieces of concept art from Half-Life 2: Episode 3. The images were supposedly created in 2008 and would have shaped the look of Episode 3 - the third episodic add-on to Half-Life 2 that never emerged from Valve.

Obviously, the content of the images is somewhat spoilerific, but does seem to show Alyx wearing her dead father's clothes. Which is a bit morbid and weird if you ask us. But we still love her.

Even if the images are real, they're quite old now so there's no guarantee whatever the next Half-Life instalment comes from Valve will contain anything even vaguely related to the scenes shown in these pictures. Still, it's the biggest Half-Life news since The Orange Box, and, assuming it is real, could give us our first insight into what Half-Life 3 contains.
